EV Charging Cost Calculator 2026 — How Much Does It Cost to Charge an Electric Vehicle?
Electric vehicles (EVs) are significantly cheaper to operate than gas cars. The average EV costs about $500-$600 per year in electricity, compared to $1,800-$2,400 per year for gasoline in a comparable vehicle. That's a savings of $1,300-$1,800 per year — or $6,500-$9,000 over 5 years. Our free EV charging cost calculator helps you estimate your charging costs based on your vehicle's battery size, driving habits, local electricity rates, and how much you use public vs home charging.
How EV Charging Costs Work
Unlike gas cars where cost per gallon is straightforward, EV charging costs depend on where and when you charge:
- Home charging (Level 1/Level 2): Uses your household electricity rate, typically $0.10-$0.30/kWh. Most EV owners do 80%+ of charging at home.
- Public charging (Level 2): Usually $0.20-$0.35/kWh or $1-$3/hour. Found at workplaces, shopping centers, and parking garages.
- DC Fast Charging (Level 3): $0.30-$0.60/kWh or $15-$30 per session. Tesla Superchargers, Electrify America, EVgo. Typically 2-3x home charging cost.
- Free charging: Many workplaces, hotels, and some businesses offer free Level 2 charging as an amenity.
Electricity Rates by State (2026)
Your home charging cost depends on your local electricity rate, which varies significantly by state:
- Lowest rates: Idaho ($0.10/kWh), Louisiana ($0.11/kWh), Washington ($0.11/kWh), Utah ($0.11/kWh), Kentucky ($0.12/kWh)
- Highest rates: Hawaii ($0.33/kWh), California ($0.27/kWh), Alaska ($0.24/kWh), Connecticut ($0.24/kWh), Massachusetts ($0.24/kWh)
- US average: $0.16/kWh
Even in California (high electricity rates), an EV is still cheaper to operate than a gas car because California also has the highest gas prices ($4.80/gal).
EV vs Gas Vehicle: Annual Cost Comparison
Here's how much you can save by switching from a gas car to an EV (assuming 13,500 miles/year):

- EV (home charging at $0.16/kWh): $540/year in electricity
- EV (20% public at $0.48/kWh): $702/year
- Annual savings (home charging): $1,350/year
- 5-year savings: $6,750
- 10-year savings: $13,500
